D2 lymphadenectomy is currently the worldwide standard operation for locally advanced gastric cancer and D2+ is an option for some selected patients. The D2 plus lymphadenectomy includes No.8p, No.10, No.11d, No.12b, No.12p, No.13, No.14v, No.16a2 and No.16b1. Dissection of these groups of lymph nodes may cause related complications. Postoperative complications that can cause prolonged inflammation have significant impact not only on mortality but also on overall survival of patients with gastric cancer even if the tumor is resected curatively...

Radical surgery of gastric cancer (D2 lymph node dissection) as the standard operation is widely used in clinical practice and satisfactory prognosis can be obtained in patients who receive radical gastrectomy. But surgical invasion can cause high morbidity of complications and mortality. The data of large-scale evidence-based medical clinical trials and large databases in Japan and Korea showed that anastomotic leakage, pancreatic leakage and abdominal abscess were the most common complications after gastrectomy, and the morbidity of complication was about 20% and mortality was about 1%...

Since the description of Candida orthopsilosis and C. metapsilosis in 2005, several methods have been proposed to identify and differentiate these species from C. parapsilosis sensu stricto. Species-specific uniplex polymerase chain reaction (PCR) was performed and compared with sequencing of the D1/D2 region of the LSU 28S rDNA gene, microsatellite typing of C. parapsilosis sensu stricto, and PCR-restriction fragment length polymorphism patterns in the ITS1-5.8S-ITS2 region of the rDNA gene. There was agreement between results of testing of 98 clinical isolates with the four PCR-based methods, with 59 isolates identified as C...

A microcalorimetric method has been combined with a potentiostatic method to measure simultaneously the rate of heat evolution and the electrical current in a powdered sample of palladium during thermokinetic oscillations accompanying the sorption of deuterium in the metal. Deterministic chaos has been confirmed in the temporal variations in current (of ca. 1-4 mA) on the onset of both the sorption and the desorption of deuterium from Pd. It has been found that the first derivative of the current in time, dI/dt, turns out to be correlated precisely with the periodicity of thermokinetic oscillations...

The dopaminergic system plays an essential role in various functions of the brain, including locomotion, memory, and reward, and the deregulation of dopaminergic signaling as a result of altered functionality of dopamine D2 receptor (DRD2) is implicated in multiple neurologic and psychiatric disorders. Tetraspanin-7 (TSPAN7) is expressed to variable degrees in different tissues, with the highest level in the brain, and multiple mutations in TSPAN7 have been implicated in intellectual disability. Here, we tested the hypothesis that TSPAN7 may be a binding partner of DRD2 that is involved in the regulation of its functional activity...

Arsenic trioxide (As2O3) has been used clinically as an anti-tumor agent. Its mechanisms are mostly considered to be the induction of apoptosis and cell cycle arrest. However, the detailed molecular mechanisms of its anti-cancer action through cell cycle arrest are poorly known. Furthermore, As2O3 has been shown to be a potential DNA methylation inhibitor, inducing DNA hypomethylation. We hypothesize that As2O3 may affect the expression of cell cycle regulatory genes by interfering with DNA methylation patterns...

Asymmetric dimethylarginine (ADMA) has been recognized as an independent prognostic factor for sepsis mortality in intensive care units. No data are available on kinetics or prognostic value of ADMA in hematological patients. We evaluated the ability of ADMA to act as a predictor for complicated course of febrile neutropenia, defined as bacteremia and/or septic shock in adult hematological patients receiving intensive chemotherapy. This prospective study included 87 adult hematological patients with febrile neutropenia after an intensive chemotherapy for acute myeloid leukemia (AML) or after an autologous stem cell transplantation (ASCT)...

The extent of lymphadenectomy in gastric cancer (GC) surgery has been for long time a matter of debate. Randomized trials performed in the West reported worse results of D2 dissection, in terms of postoperative complications and long-term survival benefit, than Eastern series and observational studies from specialized Western centers. However, long-term re-evaluation of such trials and in depth-analysis of other experiences demonstrated the potential benefit of D2 in reducing the probability of cancer-related death and the safety of this procedure when avoiding unnecessary spleno-pancreatectomy and in centers with ad adequate surgical volume...

Schizophrenia is a chronic mental disease that affects nearly 1% of the population worldwide. Several lines of evidence suggest that the dopaminergic (DAergic) system might be compromised in schizophrenia. Specifically, the mixed dopamine (DA) D1/D2 receptor agonist apomorphine induces schizophrenia-like symptoms in rodents, including disruption of memory abilities. Crocins are among the active components of saffron (dried stigmas of Crocus sativus L. plant) and their implication in cognition is well documented...

The auditory cortex (AC) dynamically regulates responses of the Organ of Corti to sound through descending connections to both the medial (MOC) and lateral (LOC) olivocochlear efferent systems. We have recently provided evidence that AC has a reinforcement role in the responses to sound of the auditory brainstem nuclei. In a molecular level, we have shown that descending inputs from AC are needed to regulate the expression of molecules involved in outer hair cell (OHC) electromotility control, such as prestin and the α10 nicotinic acetylcholine receptor (nAchR)...
